2020-10-21syscall: only compile ptrace varargs shim on LinuxNikhil Benesch1-1/+1
Only compile the __go_ptrace varargs shim on Linux to avoid compilation failures on some other platforms. The C ptrace function is not entirely portable (e.g., NetBSD has `int data` instead of `void* data`), and so far Linux is the only platform that needs the varargs shim. Additionally, make the types in the ptrace and raw_ptrace function declarations match. This makes it more clear that the only difference between the two is that calls via the former are allowed to block while calls via the latter are not.

PR97360 shows a problem in how we create our PXI and POI modes that cause an ICE in the ranger pass.

2020-10-21Inline functions with builtin_constant_p more agressively.Jan Hubicka4-5/+117
This patch implements heuristics that increases inline limits (by the hints mechanism) for inline functions that use builtin_constant_p on parameter. Those are very likely intended to be always inlined and simplify after inlining. The PR is about a function that we used to inline with --param inline-insns-single=200 but with new default of 70 for -O2 we no longer do so. Hints are currently configured to bump the bound up twice, so we get limit of 140 that is still not enough to inline the particular testcase but it should help in general. I can implement a stronger bump if that seems useful (maybe it is). The example is bit operation written as a decision chain with 64 conditions. This blows up the limit on number of conditions we track per funtion (which is 30) and thus the size/time estimates are not working that well. gcc/ChangeLog: PR ipa/97445 * ipa-fnsummary.c (ipa_dump_hints): Add INLINE_HINT_builtin_constant_p.

2020-10-21Introduce vxworks7r2 support for ppc and ppc64Douglas Rupp2-81/+173
This change introduces support for the most recent versions of VxWorks on PowerPC targets, for both 32 and 64 bit thanks to a bi-arch setup. The system compilers are essentially configured as Linux toolchains with only a few specificities and we replicate that model here. The most visible specificities are the use of secureplt by default, the pre-definition of some macros that the system headers still rely on (_VX_CPU and _VX_CPU_FAMILY, for example), and of course some variations related to the so VxWorks typical kernel vs RTP mode distinction. In addition to the introduction of config.gcc and libgcc configuration chunks, much inspired by the linux ones, the change - Reworks rs6000/vxworks.h file to feature bits common to the Vx6 and Vx7 port then a separate section for each, where the Vx7 part is very short as we rely on the Linux definitions for most things. - Adjusts the CPU macro predefinitions in CPP_SPEC to resort to "_VX_CPU" instead of "CPU" for Vx7, to better match the more recent system headers expectations, - Adds a cpu definition case for e6500. - Changes to the use SUB3TARGET_OVERRIDE_OPTIONS instead of SUBSUBTARGET_OVERRIDE_OPTIONS for specifics, so we don't override the Linux's version of the latter for vx7. 2020-10-20 Douglas Rupp <rupp@adacore.com> gcc/ * config.gcc (powerpc*-wrs-vxworks7r*): New case. * config/rs6000/vxworks.h: Rework to handle VxWorks7.

2020-10-21phiopt: Optimize x ? __builtin_clz (x) : 32 in GIMPLE [PR97503]Jakub Jelinek2-24/+95
While we have at the RTL level noce_try_ifelse_collapse combined with simplify_cond_clz_ctz, that optimization doesn't always trigger because e.g. on powerpc there is an define_insn to compare a reg against zero and copy that register to another one and so we end up with a different pseudo in the simplify_cond_clz_ctz test and punt. For targets that define C?Z_DEFINED_VALUE_AT_ZERO to 2 for certain modes, we can optimize it already in phiopt though, just need to ensure that we transform the __builtin_c?z* calls into .C?Z ifns because my recent VRP changes codified that the builtin calls are always undefined at zero, while ifns honor C?Z_DEFINED_VALUE_AT_ZERO equal to 2. And, in phiopt we already have popcount handling that does pretty much the same thing, except for always using a zero value rather than the one set by C?Z_DEFINED_VALUE_AT_ZERO. So, this patch extends that function to handle not just popcount, but also clz and ctz. 2020-10-21 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/97503 * tree-ssa-phiopt.c: Include internal-fn.h.

This simplifies the maps between original and new basic blocks and loops as used for CFG copying. Instead of using a pointer hash table to allocated mapping entries use a hash_map with int_hash, removing the indirection and code duplication.
